Mnemonic training has potent and enduring effects on memory capacity. Participants in the mnemonic condition showed significantly greater improvement in memory performance after training than participants of the active and passive control groups (p<.001, η²=.3 each, no significant difference between control groups). Mean changes from pre- to post-training sessions in free recall of 72 learned words ± standard error of the mean are shown. During a four month follow-up, subjects re-encoded the list of words from their baseline visit and were asked to recall the list after a 15 minute delay.
